The Tigers had chances to win the game, but they had Eldin Jakupovic to thank for saving a point when the keeper made a brilliant save from Tom Ince with five minutes left.
The draw keeps Hull in second place in the Championship, but Bruce was left fuming by the playing surface.
Bruce said: "The pitch was terrible, an absolute quagmire.
"People pay good money to watch good football and Blackpool try to play an attractive game but the pitch is so slow and horrible, it's a mess.
"It was difficult to move the ball and impossible to run with it.
"I thought we were better in the second half and looked a bit more lively, but it is another point and who knows where it could take us.
"We keep getting the results and I can't fault our resilience but we had two good chances to win it.
"But the most important thing is that we secure who we have already got as we have put ourselves in a great position with 20 games to go.
"We need to handle any pressure if we are going to be successful."
